From: Coherent resonance in the distributed cortical network during sensory information processing
Experimental results demonstrating coherence resonance near perception thresholds. (A) Schematic illustration of the experimental protocol. (B) (Upper panel) Number of EEG channels with maximal correlation time versus image contrast for different subjects (each curve corresponds to one participant in the experiment). The most local maxima are concentrated in areas I and III corresponding to image recognition and portrait identification, respectively. (Lower panel) Distributions of the coherent channel among participants. (C) Brain coherence for different image contrasts: (I) \(I=0.1\), (II) \(I=0.4\), (III) \(I=0.7\), and (IV) \(I=0.8\) for one typical subject.
